Note: midway through the puzzle I noticed a cell that had candidates in it, but that should have been solved, so I don't know if it would have affected my solution.
Type 2 UR (68) boxes 79; r2c7, r7c8<>7
Multi-coloring (5). Skyscraper in rows 16; transport 5 from r1c5 to r9c6; r9c8<>5 |

With the benefit of hindsight and your grid, I see that the Multi-coloring move on 5 was a one-stepper. |
